About this toolkit
Japan Trip Toolkit is built for first-time and repeat visitors who want help with the specific Japan-only questions that generic travel widgets ignore: which shinkansen seat to pick, when an onsen will refuse a tattoo, whether a 7-day JR Pass actually pays off, when sakura will bloom in Kyoto in a given year, what to do at an izakaya if you can't read Japanese, and so on. Every tool here is built around a Japan-only edge case the author or a contributor has personally hit. We do not collect personal data, we do not run trackers, and we do not auto-refresh anything. Prices and schedules use 2026 reference data; always double-check on official sources before paying.

You can opt out of personalized Google ads at adssettings.google.com or via aboutads.info. Some calculators run entirely in your browser; nothing you enter is sent to any server. If we add third-party embeds later (YouTube, Maps), they are clearly marked and load only after you click.
